Relationship of the preferred vertical dimension of occlusion to the height of the complete dentures in use
The dependence of the preferred vertical dimension of occlusion (PVDO) of edentulous subjects on the height of the complete dentures the subjects were wearing was investigated. Two experiments were carried out. Experiment I tested whether PVDO is influenced by a change in the vertical dimension of occlusion of the dentures. Experiment II compared PVDO values before and after insertion of dentures that had been constructed with an occlusal vertical dimension equal to PVDO. It is concluded that PVDO is independent of the height of the complete dentures the subject is wearing. Clinical implications are discussed
SpecNet revisited: bridging flux and remote sensing communities
Spectral Network (SpecNet) began as a Working Group in 2003 with the goals of integrating remote sensing with biosphere-atmosphere carbon flux measurements and standardizing field optical sampling methods. SpecNet has evolved into an international network of collaborating sites and investigators, with a particular focus on matching optical sampling tools to the temporal and spatial scale of flux measurements and ecological sampling. Current emphasis within the SpecNet community is on greater automation of field optical sampling using simple cost-effective technologies, improving the light-use-efficiency (LUE) model of carbon dioxide flux, consideration of view and illumination angle to improve physiological retrievals, and incorporation of informatics and cyberinfrastructure solutions that address the increasing data dimensionality of cross-site and multiscale sampling. In this review, we summarize recent findings and current directions within the SpecNet community and provide recommendations for the larger remote sensing and flux communities. These recommendations include comparing the LUE model to other flux models driven by remote sensing, considering a wider array of biogenic trace gases in addition to carbon dioxide, adoption of standardized and automated field sensors and sampling protocols where possible, continued development of cyberinfrastructure tools to facilitate data comparison and integration, expanding the network itself so that a greater range of sites are covered by combined optical and flux measurements, and encouraging a broader communication between the flux and remote sensing communities

Net ecosystem exchange of CO2 with rapidly changing high Arctic landscapes
High Arctic landscapes are expansive and changing rapidly. However, our understanding of their functional responses and potential to mitigate or enhance anthropogenic climate change is limited by few measurements. We collected eddy covariance measurements to quantify the net ecosystem exchange (NEE) of CO2 with polar semidesert and meadow wetland landscapes at the highest latitude location measured to date (82°N). We coupled these rare data with ground and satellite vegetation production measurements (Normalized Difference Vegetation In
